In short: Ramzi Yousef, the mastermind behind the 1993 World Trade Center attack, intended to topple one tower into the other to maximize casualties. While the explosion killed six people and injured over 1,000, the structural collapse he envisioned did not occur. It would later serve as a blueprint for future terrorism.

The 1993 plot began in late 1992 when Ramzi Yousef arrived in the United States from Pakistan. Despite traveling on a questionable Iraqi passport and being detained for lacking a visa, he was released into the country while awaiting an asylum hearing. He soon joined conspirators in New Jersey, where they established a bomb factory in a rented apartment and stored chemicals in a locker. Over several weeks, they assembled a 1,500-pound device enhanced with hydrogen gas tanks, intended to amplify the blast's destructive power.

On February 26, 1993, the group detonated the bomb in a basement parking garage beneath the World Trade Center. The explosion created a crater six stories deep and 200 feet wide, filling the building with smoke and debris. While the immediate goal of bringing down the towers failed, the attack marked a significant escalation in terrorism on American soil. Investigators later discovered that Yousef had planned the strike to cause a chain reaction, with the collapse of the North Tower intended to destroy the South Tower as well.

The investigation moved quickly after authorities recovered a piece of the van's chassis from the rubble, which contained a vehicle identification number. This led the FBI to a rental agency in Jersey City, where Mohammad Salameh was arrested while attempting to reclaim his deposit. While several conspirators were apprehended and convicted by 1994, Yousef fled the country on the evening of the attack. He remained at large for two years before being captured in Pakistan in 1995. His uncle, Khalid Sheikh Mohammed, would later build upon these methods to orchestrate the September 11 attacks in 2001.

The aftermath of the 1993 bombing revealed a broader network of threats. Authorities uncovered a second plot to simultaneously attack multiple New York landmarks, including the United Nations building and various tunnels. Yousef was also linked to a thwarted scheme to blow up over a dozen international airliners. The trial of his co-conspirators in 1994 involved over 200 witnesses and 1,000 exhibits, highlighting the scale of the conspiracy that had been operating in plain sight.
